Each year on February 22nd, Girl Guides and Girl Scouts all over the world celebrate World Thinking Day. World Thinking Day was first created in 1926 at the 4th Girl Guide/Girl Scout International Conference, held at Girl Scouts of the USA’s Camp Edith Macy (now called Edith Macy Conference Center). Conference attendees decided that there should be a special day when Girl Scouts and Girl Guides all around the world think of each other and give thanks and appreciation to their “sister” Girl Guides and Girl Scouts.

The delegates chose February 22nd as the date for World Thinking Day because it was the mutual birthday of Lord Baden-Powell, founder of the Boy Scout Movement, and his wife Olave, who served as World Chief Guide.

In 1932, at the 7th World Conference, held in Poland, it was suggested by a Belgian delegate that since birthdays usually involve presents, girls could show their appreciation and friendship on World Thinking Day not only by extending warm wishes to each other but also by offering a voluntary contribution to the World Association. This is how the World Association's World Thinking Day Fund began. The fund helps offer Girl Guiding/Girl Scouting to more girls and young women worldwide. Girl Scouts of the USA, through its Juliette Low World Friendship Fund contributes to the World Thinking Day Fund.
